FILLING REPLENISHING LOOM.

Application filed May 2, 1927.

This invention relates to filling replenishing looms and particularly to means for preventing sloughing or displacement of the yarn upon the filling carriers in the hopper.

In the prior patent to John T. Kirk, N 0. 1,595,045, granted August 3, 1926, there Was shown and described an anti-sloughing device which acts upon the mass of filling on the fillihg carriers in the hopper and prevents endwise displacement thereof. The present invention is a further development of the anti-sloughing device shown and described in the Kirk patent above mentioned.

Filling carriers which are used in the shuttle for laying the filling or weft thread in the shed, are now usually formed with conical or filling wind, and since the conical end portions of the mass of filling on the filling carriers may vary somewhat in size and shape, the present invention is directed to an anti-sloughing device which will automatically conform itself to the contour of the filling on the filling carriers and prevent displacement of the yarn thereon.

' In accordance with the present invention,

the pad which constitutes the filling engaging element of the anti-sloughing device 13 of generally circular form adapted for use in the well-known rotary hopper, and in order that the pad may automatically conform itself to the filling carriers when they are placed in the hopper, the present invention provides means for supporting the pad for endwise movement between the supports to form cradles or seats in which the end windings of the filling carriers or bobbins rest. The supports for the pad are, in accordance with the present invention, located between the tip end supports for the filling carriers in the hopper and are preferably secured directly to the hopper itself,

one at each side of a filling carrier. 7

The invention and new features thereof will best be made clear from the following description and the accompanying drawings of one good form thereof.

In the drawings:

Fig. 1 is a perspective view at the replenishing side of the loom, showing a hopper for filling carriers containing the present Serial No. 188,245.

of inserting the pad in the supports for endwlse movement relative thereto.

The loom frame 1 may be of usual construction and 'mounted on the upper part of the loom frame is the hopper stand 2 having the end or cover plate 3 in which is mounted the stud or shaft 4 for the support of the rotary hopper, which comprises the end the tip end holders to press endwise upon the filling carriers. These parts may be of usual construction and need no further explanation.

Extending from the hopper stand is the studor dead shaft 11 on which mounted the transferrer 12 having a downwardly extending portion 13 connected to a dog 14 which on call for replenishment of filling is engaged by a hunter onthe lay, as usual in this type of replenishing loom, to transfer a filling carrier from the hopper to the shuttle and eject the depleted fillingcarrier from the shuttle. These parts, also, may be of usual construction.

Secured to the end member 6 of the rotary hopper isthe series of pad supports, one of such supports being preferably located between the filling carrier tip supports 8, and mounted in the pad supports for free endwise movement is the pad 15.

' Each pad support is preferably formed as I a yielding member, and, as shown more clearly in Figs. 2 and 3, comprises the plate 16 having an upstanding arm 17 which may be appropriately secured to the end member 1 6 of the hopper as by one or. more screws 18.

The plate 16 is preferably formed of spring metal and has its end portion 19 turned up- 'wardly to provide a loop 20 which embraces the pad 15 transversely between each of the filling carriers in the hopper.

The pad supporting loop 20 is formed with a gate 21 which underlies the pad 15, as indicated in Fig. 2, when the pad is in and supported position in the loop of the pad supports. The horizontally extending portion 22 of the loop has a shoulder 23 preferably formed by pending the pad support, as shown, so that theend of the gate 21 when in closed position, as" indicated in Fig. 2, will underlie the pad in the recess formed by the shoulder.

As hereinbeforc mentioned, the pad 15 is of generally circular form and may take the shape of a ring. When the pad 15 is to be placed in position on the pad supports, it is pushed edgewise, Fig. 3, so that the enteringedge portion of the pad lifts the yielding gate 21 to permit the pad to be torced into the pad supporting loops, and when the pad is in final position, the gate 2i automatically closes, by reason of its spring action, to therebymaintain the pad in the supporting loops with permissive movement of the pad lengthwise or circularly. The pad.

is formed of yielding material, such as woven fabric, felt, or other appropriate material, so that when it is placed in the pad supports, as hereinbefore described, it will bend .or double up to a degree, and then spread out into its supporting position, as indicated in Fig. 2.

Hoppers of therotary type for containing filling carriers are charged or supplied from time to time with the filling carriers, and when the filling carriers are placed in the hopper the yielding pad engages the mass of filling on the filling cz'urriersand automatically conforms tothe size and shape of the wound mass offilling; by the permissive movement of the pad lengthwise in the pad supports. I

As described in the Kirk patent, hereinbefore mentioned, the transferrer is provided with a hunter 24, Fig. 1, which engages the filling carriers when the transferrer is operated, and is located inward of the edge of the pad, so that the pad itself does. not interfere with the proper transfer of filling carriers during replenishment of filling. The formation of the pad supports, as

.hereinbefore described, as of sheet metal or similar material having resiliency of its own,- affords an appropriate yielding support for the pad, while the permissive lengthwise movement of the pad in the loops of the pad supports permits the pad to automatically conform to the shape and size of the mass of filling on the filling carriers engaged by it. The gate which closes the loops of the pad supports when the pad has been placed in operativeposition, prevents edgewise movement of the pad from its loosely supported position in the loops of the pad supports.

What is claimed is:

1. In a. filling replenishing loom, the combination of rotary hopper having supports for fillingcarriers, apad which bears upon the mass of wound filling on the filling carriers to prevent 'sloughing or displacement of the filling, and pad supports provided with loop portions which loosely support the padfor movement relative thereto that the fillingengagingportions of the pad may eonform to the contour of the mass of filling engaged by it.
